Browser-safe networking helpers built around urlBuilder: a
tolerant URL coercion + chainable builder that gracefully handles
partial inputs (bare hosts, path-only strings, { url } wrappers),
a small IPv4 / IPv6 address + CIDR toolkit (parsing and membership
lookups), and email-address parsing (parseEmails /
isEmail) that normalizes the CSV / single-string / array
inputs email recipient and allow-list fields accept into a clean
string[]. No node-only imports, so this module is the canonical
home for anything URL-, IP-, or email-shaped that also has to run in
a Vite / Webpack / esbuild client bundle. Node-only network helpers
(e.g. DNS resolution) belong in a node-tagged package, not here.
